Manage System Alerts

System alerts are internal health checks that monitor the health of Ops Manager itself, including the health of backing databases, Backup Daemons, and backed-up deployments. Ops Manager runs health checks every five minutes.

To view the list of system alerts:

  1. Click the Admin link at the top of the Ops Manager UI.
  2. Click the Alerts tab.
  3. Click the Open Alerts link under System Alerts.

Disabled system alerts are grayed out.

If you have the Global Roles or Global Roles roles, you can modify notification settings or disable a system alert.

System Alert Components

Each system alert consists of three components:

Component Examples
A condition that triggers the alert
  • A blockstore is using too much disk space.
  • An Ops Manager backing database had startup warnings.
A list of recipients of the alert
  • Ops Manager user or role: Ops Manager Administrators
  • Email address: admin@example.com
  • Slack channel: #alerts
A method by which the alert is sent
  • Email
  • Slack
  • SMS

When the alert is enabled and its trigger condition is met, Ops Manager sends an alert to the specified recipients using the specified medium for that alert. For a list of the notification options, see the Select the alert recipients and delivery methods step in the Modify Notification Settings for a System Alert procedure on this page.

By default, Ops Manager enables all alerts and sends the alerts to the email address specified in the Admin Email Address field in the Ops Manager configuration options.

Available System Alerts

Ops Manager provides the following system alerts:

Alert Processing

Alert Type Alert Message Description
ORDINARY_ALERT_PROCESSING_DISABLED

Alert Type Alert Message Description

Sent when the Backup Daemon has fallen so far behind in applying oplog entries that Ops Manager has extended the period of time it stores the oplog entries. By default, Ops Manager stores oplog entries in the Oplog Store for 24 hours.

If the Daemon has not yet applied an oplog entry an hour before its expiration, Ops Manager extends the storage period for another three hours. Ops Manager can continue to extend the storage period up to 14 days.

If you receive this alert:

  1. Check that your Backup Daemon is running.
  2. Check that your Backup Daemon runs on sufficiently performant hardware to apply oplog entries in a timely manner.
